2 Claims. (Cl. 24*198) This invention relates to clothing,.and more particularly to a slide unit for forming a loop on a length of strap in automatically gripping, binding and manually adjusted position thereon.

There has been for some time in the industry a demand for a slide unit which would operate in the highly effective and useful manner of the slide unit of this invention, and numerous attempts were made in the industry to provide a slide unit directed to the objectives above noted. The slide unit of the present invention attains these objectives in a novel and most satisfactory fashion, as will appear from the description and drawings.

The slide unit of the invention, as will appear from the drawings and description below, is of such structural features that the strap may be readily threaded therethrough to form a loop through which a garment portion, or a garment connector member may be passed.

The unit of this invention is of such structural features that the loop may be readily formed thereon to precisely the length desired, and, when so formed, will automatically grip and bind the slide unit; at the same time, the

strap may be readily manually released or adjusted from time to time as may be desired.

These and other advantageous objects, which will appear from the drawings and from the description hereinafter, are accomplished by the structure of my invention, of which an embodiment is illustrated in the drawings. It will be apparent, from a consideration of said drawings and the following description, that the invention may be embodied in other forms suggested thereby, and such other forms as come within the scope of the appended claims are to be considered within the scope and purview of the instant invention.

In the drawing:

Fig. 1 is a plan view of a blank formed from a sheet of material to form a unit having the outline of a flattened 8,

Fig. 2 is a partly sectional plan view, showing a step in the method of the invention for cutting oppositely angled adjacent faces of alternate teeth along parallel outer edges of the apertures of said unit, the latter being shown in dotted lines,

Fig. 3 is a similar view showing the next step in the method, wherein the blank with the thus formed alternate teeth is acted on by a die to impress the complementary oppositely angled adjacent faces of alternate teeth,

Fig. 4 is a fragmentary plan view of the unit formed pursuant to the step illustrated in Fig. 2,

Fig. 5 is a similar view of said unit in the step illustrated in Fig. 3,

Fig. 6 is a plan view of the unit after the same has been subjected to the steps of Figs. 2 and 3,

Fig. 7 is a transverse sectional view, taken on line 77 of Fig. 6,

Fig. 8 is a perspective view of the unit shown in Fig. 6, completed pursuant to additional steps of the method of the invention,

v are bent upwardly as noted at 38 and 39 in Fig. 8.

'ice

Fig. 9 is a transverse sectional view, taken on line 9-9 of Fig. 8, and

Fig. 10 is a medial sectional view of the completed unit, showing the manner in which the clothing loop on a clothing strap is formed thereon.

As shown in the drawings, the slide unit of the invention is initially fabricated as a blank 10 from a suitable sheet of material such as a metal, to provide a pair of parallel elongated apertures 11, 12, said blank being provided with a generally corresponding outer edge 13, thereby providing a unit of generally flattened 8 outline. In the next step of the method, oppositely angled adjacent faces 14, 15 of alternate teeth (Figs. 4 and 5), as, for example, the alternate teeth 18, 19, 20, shown in Fig. 6 are formed as illustrated at Fig. 2, by a suitable means, such as, for example, the die member provided with the oppositely angled adjacent face-forming projections 26 to form the adjacent faces, 14, 15 of alternate teeth shown in Fig. 4. In the next step in the process illustrated in Fig. 3, means such as a die member 27 provided with oppositely angled face-forming projections 28 spaced to complement the oppositely angled face-forming projections 26 of the die 25, is provided; in the step of the operation illustrated in Fig. 3, the complementary oppositely angled adjacent faces 15a, 14a (Fig. 5) which with the previously formed adjacent faces 15, 14 of the first stage of the method shown in Figs. 2 and 4 are formed, to form the complete intermediate tooth portions designated in Fig. 6 as 18a, 19a between the alternate tooth portions 18, 19 and 20. Thus, by the method described and shown in Figs. 2, 3, 4 and 5, a unit is provided with complete rows of teeth 29, 30 at the outer edges of the apertures 11 and 12. In the next step of the method, the blank is formed from the single plane disposition thereof shown in Figs. 6 and 7 to its final form illustrated in Fig. 8. Following the Figs. 3 and 6 step, the rows of teeth 29, 30 are bent upwardly at an acute angle 31 to the plane 32 of the base of the article (Fig. 9). The projected planes 33, 34 of rows of teeth 29, 3t) meet to define an acute angle 35 as shown in Fig. 9. The rows of teeth are further formed of such length that when so bent upwardly, their points will intersect the plane of the outer edges of the article, as noted at 36 and 37 of Fig. 9. The edges of the apertures not provided with the teeth 29, 30 The outer edge 13 of the article is also bent upwardly as noted at 40. The portions 38, 39 and 40 are preferably bent at substantial right angles to the plane 32 of the article, as shown in Fig. 9.

The slide unit formed as above noted, embodying the invention, is highly eificient and practical in operation. The clothing strap on which the loop 46 is to be formed to receive the member 47, which may, for example, be a garment-holding member, is passed over the outer edge 40 of the article, over the row 29 of teeth and under the bar 41 of the article defined by the upturned inner edges of the apertures 11 and i2, and over the row 30 of teeth and thence over the outer edge 49 of the unit. Then the strap is doubled upon itself to form the loop 46 and brought around and under the bar 41 and over the row of teeth 30. The free end 48 of the strap 45 is disposed within the loop portion 46; the upper end of the strap would normally be secured to one part of the garment; the tendency in the normal use of the garment would be to draw said end of the strap upwardly in the direction indicated by the arrow 49. The loop end 46 of the strap would serve as a support for the other portion of the garment secured to the member 47, which would serve to stress the loop 46 in the direction indicated by the arrow 50 in Fig. 10. Thus, in use, the normal stresses 49. 50, to which the strap is subjected, will serve to simply more tightly bind the same on the points 36, 37 on the rows of teeth 29, 30, which will, as shown in Fig, 10, after the formation of the strap loop and the adjustment of the strap on the slide unit of the invention bite into the material of the strap; the strap will wedge itself intermediate the bar 41 and rows of teeth 29, 30, and over the outer edge 40 of the article. Thus the strap will be automatically locked in adjusted position and the slide unit of this invention will have a binding gripping action on the strap and its loop. Any attempt to move the ends of the strap apart as shown at 49 and 50, will simply further grip and bind the parts unto the strap. Even an intermittent reciprocation of the ends of the strap toward and away from each other will not dislodge the position of the strap in the slide unit. To alter the position of the strap thereon, it will be necessary to manually move the strap parts as desired. But the action of dislocation would not be attained automatically or in normal use. The effectiveness of the strap unit is attributable to the specific features of construction and relative disposition of the parts above described and shown in the drawings and forming the subject matter of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A slide unit for forming a loop on a length of clothing strap in automatically gripping and binding but manually adjustable position thereon, comprising an article having a flat base and provided with a pair of elongated, parallel apertures and with an outer edge forming, with said apertures, a unit of generally flattened 8 shape, and continuous rows of teeth in said article formed at the outer edges of said apertures and upwardly directed relative to the plane of said base at an acute angle thereto, the inner edges of said apertures being upwardly directed rela- 4 tive to the plane of said base and being so proportioned as to extend upwardly to a point substantially below the plane of the points of said teeth.

2.
